Introduction to Locker Security System in Advanced Banking Using Efficient OTP Generation Using Stream Cipher with Random Digit Project:

In recent days security is the most important for everyone and everything. Without security we can’t do anything because hacking is done by the unknown persons, so we are lost our properties, money, things, etc. it is done mainly in online system (banking systems) because most of the business persons, working people, busy persons, etc will do the transactions through online so hacking of passwords are easy. Mainly ID and Password is the most important for the internet. Compare to other methods it is easy way. it is a vulnerable method against attacks such as eavesdropping or relay attack.

To overcome this problem, OTP technique method is used. The most popular algorithm is HOTP algorithm based on one-way hash function SHA-1. But the recent researchers have found the weakness of hash function, so we have to replace a new algorithm i.e., “PING PONG-128”, which is a onetime key password. It is created for not only security but also more efficiency to satisfy the need for light weight algorithm. And also “RANDOM DIGIT” is used for creating variable with a digit of OTP.

This algorithm is mainly for safe deposit lockers. For the password generation “OTP generation using steam cipher with random digit” is used. Software requirements are ASP/Asp.Net 2.0 and SQL server 2000, VB script, java script. Ping pong-128 is a specific cipher from ping pong family. It has 128-bit initialization vector, has 257 bits of internal state and achieves a security of 128 bits.

For cryptography one of the algebraic structures is “QUASIGROUP”. It has both encrypted and decrypts the user data. Secure message is also available. If the transaction is done then the encrypted message will go to the mobile of the user and also server. Password has validity, if cross the validity message will sent to the user mobile. So attacks are not possible and we will secure our deposit lockers.
